Abstract


The extraction of fat from snail has been carried out by Soxhlet extractor with petroleum ether solvent. Fatty product from extraction was transesterificated in BF3/methanol solvent for an hour by reflux procedure, then extracted by n-hexane to produce methyl ester fatty acid. Free water fatty acid methyl ester was analyzed by Gas Chromatography-Mass spectrometer (GC-MS). Fatty acid ester was separated from its fractions use column chromatography in n-hexane, n-hexane:dietil eter (2:1 v/v), dietil eter, aseton, ethanol and methanol. This fractions wer also analized by GC-MS. From GC-MS data sheet can be obtained 5 fractions which details are; fraction 1 contains omega 3: 27.54 %, omega 6: 15.40 % and omega 9: 6.77 %. Fraction 2 contains omega 3: 3.08 %, omega 6: 15.62 % and omega 9: 10.72 %. Fraction 3 contains omega 6: 3.57 %, omega 9: 7.02 % and none omega 3 inside it. Omega 3, 6 and 9 can't be identification in fraction 4 and 5.
